T at w/wm it may concern: stoneis delivered betweenthe sillsontoachute Be it known that I, IRA P. CRIBB, of Canan- B, inclined downward, as usual. The elevadaigua, in the county of Ontario and State of tor is composed of a frame made in two See- New York, have invented a new Improvement tions C and D, the two sections being hinged in Elevators for Stone-Crushers; andI do heretogether upon the under side, as at E. The

The part D of the frame this specification, and represent. carries near its lower end a like drum H, and

The Fig. 3 a longitudinal central section of the width of the elevator-frame is such as to per- 5 Samemit it to pass down between the sills of the This invention relates to an improvement bed, the sills being cut away upon their inner in the construction of elevators for that class sides, as represented at K K, Fig. 2, for such of stone-crushers which are adapted to be free passage of the frame. The lower end of transported from place to place, as occasion the elevator is in such a position with rela- 20 may require, for breaking stone. It is necestion to the chute B that the stone which falls sary that the elevator should be so arranged upon the chute B may drop upon the upper as to extend below the discharge-chute frOm run of the elevator, and so that as the band the crusher and rise to a point considerably travels around the drums it Will carry the above, so that the stone delivered from the stone or crushed material upward until it 25 crusher may be carried to a higher point of reaches the upper end,where itwillbe dumped elevation for discharge.

The crushed its bed and elevator, may be readily trans- I00 ferred from place to place without any material disarrangement or detachment of the parts, and at any time when it is desired to raise the elevator for any purpose it may be easily done as described.

I do not claim, broadly, an elevator made in two or more parts hinged together so as to be contracted, as such, I am aware, broadly considered, is not new.

I claim- The combination of the sills or bed A A, adapted to receive a stone-crusher, a chute B between said sills, through which the crusher may discharge, an elevator-frame composed of two parts 0 D, the one part 0 hung upon an axis above the said sills or bed and distant from the chute, the said part 0 also carrying a drum G at its upper end, the part D hinged to the lower end of the part C and carrying a drum H at its lower end, the said frame adapted to fold up and down between the said sills, and an endless band through said frame and around the said drums, the said band carrying buckets, and the frame in its down position presenting the buckets to the chute, substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
